"Supposing I'm wrong or scientists are wrong, 97 percent of them all wrong, supposing they are, what's the worst that can happen?" he told the graduating class at Boston College.

President Barrack Obama is pressing the nation to reduce its carbon emissions and move away from using coal, which America has in abundance. Indeed, the administration says the science is settled and that "climate change is fact."

Kerry suggested that it’s a win for America no matter what.

He said: "We put millions of people to work transitioning our energy, creating new and renewable and alternative; we make life healthier because we have less particulates in the air and cleaner air and more health; we give ourselves greater security through greater energy independence – that’s the downside. This is not a matter of politics or partisanship; it’s a matter of science and stewardship. And it’s not a matter of capacity; it’s a matter of willpower.

"But if we do nothing, and it turns out that the critics and the naysayers and the members of the Flat Earth Society, if it turns out that they’re wrong, then we are risking nothing less than the future of the entire planet."

There are thousands of scientists who think differently. And many of them say their view is being shunted aside.

Just last week, Lennart Bengtsson, a research fellow at The University of Reading, revealed the backlash he suffered when he suggested more research is needed to confirm it is human actions — and natural climate cycles — that are to blame for the rise in the oceans and an increase in storm severity.

"It is a situation that reminds me about the time of McCarthy. I would never have expected anything similar in such an original peaceful community as meteorology. Apparently it has been transformed in recent years," he lamented.
